What's a little bit negative is the sound quality of the screencasts, it's really, really bad. It would be a really important improvement if you got a proper studio microphone and did some audio post-processing (I recommend https://auphonic.com/ for this kind of stuff, it's magic what they do).
Haven't done much recording before, so I'm learning the ropes. Auphonic looks really cool. I'll definitely be checking them out.
The traditional pop filter made from a pair of tights and a wire coathanger works very well too.
Also get some good closed back headphones asap, so you can monitor how you're coming in as you speak.
The next thing to think about after you're getting a decent capture is some kind of dynamics control, ie. compression, but that's beyond the scope of this comment.
Like the parent says compression is also quite important. It’s a big part of what makes radio voices sound radio, for example. Seeing it simplistically it is basically about lowering the dynamics of your sound—make the loud parts softer, so you can make the whole thing louder.
Any audio editing software comes with basic compression plugins. It takes some exercise to get right. Also, as you are making parts of your recording louder, any bad acoustics, noises artefacts are amplified.
Some recording software allows you to monitor effects while you are recording—this can help in finding the right acoustics. Of course there will always be a slight delay—a dedicated hardware compressor solves this problem.
It has honorable pricing, an unlimited trial, and every feature you could ever need. It's particularly well suited for the kind of stuff you're doing: it has ripple editing, automatic alignment of repeated takes and so on. Can't recommend it enough. Make sure to read the manual though, it uses the mouse buttons in an unusual way.

Both are valuable.
I've watched a couple of them now and, if I hadn't seen your comment, I don't think I would have given the audio a second thought.
If Chris Oliver happens to see this: nice work!
So far, the feedback from people who learned from an episode was that they didn't even notice the audio quality was bad which I'm happy about. It will improve as I have practice, but the content should matter more than the quality of audio.
Ruby Tapas[2] by Avdi Grimm is a good replacement - although it's ruby and not much rails.

It is definitely worth $9 for all of the existing great content.
